Chongzhen Undergraduates

"I'll sleep for a while, please keep an eye on it." After Zhu Youjian finished speaking, he immediately got into a carriage and fell asleep.He has become a hands-off shopkeeper, but poor Wang Chengen and Wu Ganlai have been burdened recently.Especially Wu Ganlai, this guy is like an iron man, he has survived until now, only sleeping for three hours a day.

Towards the afternoon, Zhu Youjian woke up, and the first thing he did was to order Wu Gan to come and go to bed.This one moved Wu Ganlai to tears, as if he wanted to die for Zhu Youjian immediately.

The Dezhou government finally agreed to the request for the sale, but it still refused to allow people from outside the city to enter the city. All the supplies were sent out of the city by them, and they were traded outside the city on the spot.However, what is more conscientious in the Dezhou government is that all the supplies are sold at the lowest price. It seems that Zhu Youjian was a little too careful before.The people in Dezhou obviously know that the prince here is the real prince, and they may be protecting themselves and not wanting to cause trouble.

After all, the crown prince went south, indicating that the capital was in crisis, and Shandong was close.If the prince stays in Dezhou, then the eyes of the enemy will definitely be fixed on Dezhou.With Shandong's current power, I'm afraid it will only lead to fire, and it will not be good.

Zhu Youjian saw that the people in Dezhou were not bad, so he felt compassion. He continued to send a decree to the city in the name of the prince, to the effect that if someone in Dezhou was willing to follow the prince south, then the teams outside the city would be willing to accept them. .To put it simply, if any of you want to run for your life, just run with us.It is dangerous to run alone, but it is safer to run together. The deadline given by Zhu Youjian is before tomorrow night.

"Father~ Brigadier Commander, I've already learned how to abacus." Jiu'er happily ran over with the abacus in his hand, and started to do the abacus on the spot.

"So fast?" Zhu Youjian was very surprised. It took him almost a week to learn abacus when he was a child before he memorized the formula.And it has only been three days since he gave the order.

"The brigade commander must count his words, and the people under me have also learned to count. Shouldn't you teach us economics?"

"Okay, we just want to stop here, you call your people over, I will give you the first lesson first."

"What's the first lesson?"

"Literacy!"

"Ah! Can you teach something useful, we are not illiterate."

How can anyone who studies economics not learn some mathematics.Therefore, Zhu Youjian's first class was Arabic numerals.When Zhu Youjian finished writing ten Arabic numerals with charcoal on a polished wooden board, a group of lowly young people looked at each other in blank dismay.No one knew what it was.

"Brigade Commander, what are you doing with these crooked talismans?" Jiu'er was dumbfounded when he saw such a strange symbol for the first time.

"Remember, these are numbers. They are the same as the numbers we use, but they are easier to write. In addition, this number is more meaningful. You must remember and learn them. They are the basis of economics." Zhu You Jian said while pointing at 0 with a stick emphatically.

"It's zero, which means nothing."

"Brigade Commander, why do you want to say anything if you don't have anything?"

"This is why you must pay attention to it. There is nothing. When expressing or recording, you must also write it out. Remember it, 0,"

In ancient times, people often ignored the concept of zero, especially the Central Plains culture, which did not pay much attention to science.Although the concept of zero has long been introduced in academia, in the minds of ordinary people, it does not pay enough attention to zero.Zhu Youjian's first digital class started from the application of zero.

This class lasted for a full six hours, until Zhu Youjian finished explaining the complete expressions of addition, subtraction, multiplication and division in Arabic numerals, and everyone saw that the sun had set, so they left angrily.Zhu Youjian was so tired that he grabbed the tea Wang Chengen handed over and drank it: "I'm so thirsty, my mouth is dry. I've never talked so much in one day."

"The brigade commander really knows a lot. The old slave just listened to it. The former emperor didn't understand these things at all." Wang Chengen looked at Zhu Youjian with a smile and thought: Xiao Mian, this once again proves that you are not the former emperor.

"Really!" Zhu Youjian pretended not to know, and turned his head to deal with other matters.

"Brigade Commander, your lecture is really good today. My daughter likes this knowledge very much." Jiu'er took Zhu Youjian's arm coquettishly and said, "What shall we learn in the next class?"

"After you have learned everything you just said, we will have to learn about numbers, negative numbers, decimals, algebra, functions..."

"You have to learn so much?" Jiu'er stuck out her tongue, startled.

"Yeah, I learned these things back then, but I was tossed to death. I did my homework every day, and I carried such a thick schoolbag." Zhu Youjian gestured for a thick schoolbag with his hand.

"It's a lie, the Brigadier didn't have a schoolbag at all when he was a child, only the children of ordinary people carry schoolbags."

Wang Chengen couldn't stop laughing when he heard the princess's words, and quickly lied for Zhu Youjian: "The brigade commander also had a schoolbag when he was a child, and it was so big that it could hold a pig."

"You are the pig." Zhu Youjian heard Wang Chengen's voice joking about him.

Chapter 29: Someone Joins

Early the next morning, a large amount of supplies were sent out from the city of Dezhou, including hundreds of catties of refined iron.

Among these fine irons was a large piece, weighing about six hundred catties.The craftsmen are not easy to lift, two people can't lift it, and four people can't hold it.Six hundred catties of iron is not big, just like a slightly larger stone.Six people standing together, grasping the smooth round bumps, it is really not easy to do.A few people did it for a long time, but they didn't carry the carriage.

This scene happened to be seen by Zhu Youjian. He found Bi Xiangdong and drew a few small things.Bi Xiangdong happily ran to the temporary work shed, and immediately gathered several people to study.Recently, everyone in the artisan workshop has learned that the pictures drawn by the brigade commander are usually good things.As long as you get the picture, you can make many skills that old craftsmen can't do in their lifetime.

Bi Xiangdong wished Zhu Youjian could find him with the blueprints every day, and now he was concentrating on improving the technology of the four-wheeled carriage.

Soon, a set of wooden pulleys was brought over by Bi Xiangdong. According to Zhu Youjian's arrangement, the two of them easily got the iron lump onto the car.

"Brigade Commander, this thing is really easy to use. But why can a few people lift it up easily after using this thing?" Bi Xiangdong knew that there must be a secret in it, so he hurriedly took advantage of Zhu Youjian's presence. When you are next to him, ask why.

"This~ This is a subject of knowledge. You will gather smarter young craftsmen later, and I will teach you a lesson."

The story of Zhu Youjian teaching the princess spread throughout the camp yesterday, and now Zhu Youjian has promised to give lectures to the craftsmen.All of a sudden, the whole battalion was blown up.Although everyone calls Brigadier Zhu Youjian, most people basically know that this is the emperor.To be the emperor's student was something that could not be kept in ancient times.These are disciples of the Son of Heaven, only those Jinshi who have entered the palace examination dare to call themselves disciples of the Son of Heaven.

When Zhu Youjian brought charcoal and templates to the shade of the big tree outside the city gate, he was startled by the black crowd.What's going on here, have you been watched by a strong crowd?

The people who came were not only craftsmen, but also Jiu'er and her subordinates. In addition, Wang Chengen and Wu Ganlai also stood aside with shy faces, looking at Zhu Youjian eagerly.Zhu Youjian even saw a few young soldiers from the Zhanbing Battalion who had no security duties coming, and they were still crowded at the front of the crowd.

Well, it's a lie that Zhu Youjian didn't panic, but his neck is already covered with a knife, and it's impossible to retreat.That's too embarrassing, so I just keep doing it, since few people understand it in this era, even if I talk nonsense, I can pass the test.

Zhu Youjian calmed down for a moment, and then opened his mouth slowly, starting with gravitation, and slowly talking about resistance, pressure, power, centripetal force, support force... and gave examples on the spot.Then it talked about the pulley block, and the decomposition of the pulley block and so on.

"Miss, why don't you tell the brigade commander why he doesn't talk about poetry and songs? It's so boring to talk about these things." Xiaoyu and Chen Yuanyuan stood far away and listened. Xiaoyu felt very boring. They came from Jiangnan and were only used to listening to literati singing. Poems and songs.

"I think these things of his are interesting." Chen Yuanyuan was fascinated by what she heard. She never thought that there is so much knowledge in this world before she came out.

Zhu Youjian's class was not considered a success, at least he himself felt that it was not successful, and he almost didn't explain it thoroughly several times in the middle, especially when explaining gravity, because everyone didn't understand that the earth is round, and he had to Slowly talking about the difference between the geocentric theory and the heliocentric theory, and several people in the middle raised various doubts, which is completely off topic.

A good mechanics class has turned into a popular science lecture, and it is completely stuck when explaining what the center is.If he really said something about the big bang of the universe, some people probably think he is crazy right away.Currently, he can only use the planets around the solar system to spread the heliocentric theory.

Just this has left the onlookers dumbfounded.I have never heard that the earth is round, so the people below will fall down?

Fortunately, Zhu Youjian then returned to gravity to continue his lectures, which dispelled everyone's doubts.Only then did everyone realize that this was the case, and the reason they didn't fall out was because everyone was attracted to each other by a force.Zhu Youjian then did Galileo's famous experiment: two iron balls fell to the ground at the same time.

When he made people stand on the top of a tall tree and let people throw the ball, two soldiers on guard at the city gate were discussing: "What do you think the group of people outside are doing? Are they a group of lunatics? So high throw the ball and play."

"Who knows, I heard that he is a fake prince, so he is probably a liar playing tricks."

At noon that day, people came out of the city one after another in Dezhou, dragging their families with them. Among them were some officials, petty officials, and some refugees.Until the next night, the city gate suddenly opened, and an army of about 1000 people came out.

A bugle sounded from Zhu Youjian's side, and the soldiers immediately formed a battle formation.Zhu Youjian is very satisfied with the current reaction speed of these men. When the bugle was first implemented, these people were still procrastinating, and the entire formation took half an hour.Since the introduction of bugles to implement strict military orders, the speed of action of troops has been greatly improved, which is close to the level of military training in later generations.

Since Zhu Youjian had no time for training, the soldiers under Zhu Youjian were still too loose, not like soldiers at all, and probably a little stronger than bandits. If it weren't for the armor and equipment on their bodies, they would have been looked down upon by others.

The troops leaving the city of Dezhou did not form an offensive formation, but walked over slowly.

"May I ask who is the crown prince?" The leading man dressed as an official shouted loudly: "We are loyal to Ming soldiers and come to join the crown prince. Please report quickly!"

"The leader dismounts, and the troops move forward in batches, and they are not allowed to move." Zhu Youjian immediately ordered a soldier loudly.

When Zhu Youjian got the news and rushed to the scene, the prince's guard of honor had already been put on the scene.Five or six people who looked like officials were kneeling on the ground, including local officials and military generals.

"What's the situation?" Zhu Youjian asked Zhang Han beside him.

"These are indeed from the Dezhou government. The leader is Cheng Xianzhen. He is not a big official, but he has a good reputation. I met him after I entered the city. Most of his subordinates are small officials. These soldiers are also recruited by him. Yes, there are about 200 people, but they don’t have much fighting power, most of them are refugees.”

"Are you Mr. An'an?" Zhu Youjian suddenly remembered a person, Gu Yanwu.He had read a document before, saying that Gu Yanwu had a good relationship with this Cheng Xianzhen, both of them were scribes, and they cherished each other a little bit.
